Abstract
Description
Die Erfindung betrifft eine Schleifvorrichtung für Walzen eines Walzgerüstes nach dem Oberbegriff des Anspruchs 1.The invention relates to a grinding device for rolling a Roll stand according to the preamble of claim 1.
Eine derartige Schleifvorrichtung ist z. B. durch die DE-PS 34 06 160 bekannt geworden. Hier findet ein Schleifband Anwendung, das über eine aufwendige Antriebs- und Führungseinheit mit der zu schleifenden Walze in Kontakt gebracht wird. Es handelt sich dabei um nicht endloses Schleifband. Nachteilig ist, daß das Schleifband schnell von einer Vorratsrolle abgerollt ist, und anschließend umständlich umgewickelt oder erneuert werden muß.Such a grinding device is e.g. B. by DE-PS 34 06 160 became known. An abrasive belt is used here, the with an elaborate drive and guide unit grinding roller is brought into contact. These are around endless sanding belt. The disadvantage is that the grinding belt quickly unrolled from a supply roll, and then cumbersome to be wrapped or renewed.
Es sind auch schon rotierend angetriebene Schleifelemente bekannt geworden. Dabei sitzen jedoch mehrere dieser Schleifelemente, denen jeweils ein Antriebsmotor zugeordnet ist, auf einer Halterung. Die Schleifelemente werden derart angetrieben, daß sie über kurze Bereiche entlang der zu schleifenden Walze oszillieren. Dazu müssen anfällige, flexible Elektrozuführungen zu den Antrieben vorgesehen sein, die die Axialbewegungen auszugleichen vermögen.Rotatingly driven grinding elements are also known become. However, there are several of these grinding elements, the a drive motor is assigned, on a bracket. The Grinding elements are driven such that they over short Oscillate areas along the roller to be ground. To do this vulnerable, flexible electrical leads to the drives are provided be able to compensate for the axial movements.
Durch die GB-A-535 481 gehört eine Verbesserung an axial verschiebbaren Tragvorrichtungen für Schleifwalzen zum Stand der Technik, die eine sich über annähernd die gesamte Länge des zu schleifenden Werkstücks erstreckende Schleifwalze aufweist, welche über ein Handrad in axialer Richtung auf einer Führung geringfügig einstellbar ist. Ein Einsatz dieser Vorrichtung in Walzwerken und eine Schwenkbewegung der Vorrichtung an das Werkstück ausführende Antriebe werden hier nicht angeregt. GB-A-535 481 includes an improvement in axially displaceable State-of-the-art support devices for grinding rollers, the one over almost the entire length of the to be ground Has workpiece-extending grinding roller, which over a Slightly adjustable handwheel in the axial direction on a guide is. Use of this device in rolling mills and one Pivotal movement of the device to drives executing the workpiece are not stimulated here.
Die CH-A-298 599 offenbart eine Schleifvorrichtung, die auf einer Führung entlang des Werkstücks verfahrbar ist. Der Antrieb für die Drehbewegung der Schleifrolle wird hier jedoch auf der Führung mitgetragen, so daß auch dieser Antriebsmotor stets mitbewegt werden muß und sich dadurch stets im Einflußbereich des abgetragenen Schleifgutes befindet.CH-A-298 599 discloses a grinding device based on a Guide along the workpiece is movable. The drive for the Rotational movement of the grinding roller is here on the guide carried, so that this drive motor are always moved must and therefore always in the sphere of influence of the worn Abrasive goods located.
Die EP-A-03 11 820 offenbart einen schwenkbaren Spindelstock für eine Schleifscheibe, mittels dessen die Schleifscheibe zwar an das Werkstück herangeschwenkt werden kann, eine axiale Verschiebung der Schleifscheibe entlang des Werkstücks ist jedoch bei dieser Schleifvorrichtung nicht möglich.EP-A-03 11 820 discloses a pivoting headstock for a grinding wheel, by means of which the grinding wheel to the Workpiece can be pivoted, an axial displacement of the However, grinding wheel along the workpiece is in this grinding device not possible.
Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Schleifvorrichtung einfach, sicher und kostengünstig aufzubauen.The invention has for its object a generic Easy, safe and inexpensive to set up the grinding device.
Zur Lösung dieser Aufgabe werden die Merkmale des Anspruchs 1 vorgeschlagen. Dadurch wird gewährleistet, daß der Drehantrieb für das auf der Führung längsbewegliche Schleifelement in axialer Richtung ortsfest vorgesehen ist. Hinzu kommt, daß ggfs. mehrere Schleifelemente von einem Motor angetrieben werden können. To achieve this object, the features of claim 1 suggested. This ensures that the rotary drive for the longitudinally movable grinding element on the guide in axial Direction is fixed. In addition, there may be several Grinding elements can be driven by a motor.

In der Schwinge 4 ist eine Führung 7 drehbar gelagert. Auf der
Führung 7 ist ein Schleifelement 8, z. B. ein Schleifmop, drehfest,
jedoch axial verschiebbar gehaltert. Bei der Führung 7 handelt es
sich um eine längsgeschlitzte Hohlwelle 7', die über einen Zahnriemen
9 von einem Drehantrieb 10 antreibbar ist.A
In der Hohlwelle 7' ist eine Gewindespindel 11 gelagert. Die Gewindespindel
11 ist über einen Zahnriemen 12 von einem Verschiebeantrieb
13, der an der Schwinge 4 gehaltert ist, drehantreibbar. Auf
der Gewindespindel ist eine Kugelumlaufmutter 14 gelagert, die über
einen Mitnehmer 15, der die Hohlwelle 7' im Bereich deren nicht
gezeigter Schlitze durchdringt, mit dem Schleifelement 8 verbunden
ist.A threaded
Die Schleifvorrichtung arbeitet wie folgt:The grinding device works as follows:
Über den Anstellantrieb 5 kann die Schwinge 4 derart verschwenkt
werden, daß das Schleifelement 8 gegen die Walze 16 angestellt wird.
Über den Drehantrieb 10 wird die Führung 7 und damit das Schleifelement
8 in Drehbewegung versetzt. Gleichzeitig treibt der Verschiebeantrieb
13 die Gewindespindel 11.The
Werden die Führung 7 und die Gewindespindel 11 mit gleicher Drehzahl
betrieben, so verbleibt das über den Mitnehmer 15 und die Kugelumlaufmutter
14 mit der Gewindespindel 11 in Wirkverbindung stehende
Schleifelement in axialer Ruhelage. Sowie der Verschiebeantrieb 13
die Drehzahl der Gewindespindel 11 gegenüber der Drehzahl der
Führung 7 erhöht bzw. erniedrigt, verschiebt sich die Kugelumlaufmutter
14 auf der Gewindespindel 11 und verschiebt somit das
Schleifelement 8.The
Erreicht das Schleifelement eines der Enden der Führung 7, so
gelangt es in den Bereich eines der Sensoren 17, 17', die als
Schaltnocken ausgebildet sind. Die Sensoren 17, 17' beeinflussen
über eine nicht gezeigte Steuerung den Verschiebeantrieb 13 in
seiner Drehzahl in Abhängigkeit von der Drehzahl des Drehantriebes
10 so, daß sich das Schleifelement 8 in entgegengesetzter Richtung
bewegt.If the grinding element reaches one of the ends of the
Für den Fall, daß die Sensoren 17, 17' zu spät oder aus Gründen
eines Defekts überhaupt nicht schalten, ist beidseits auf der
Gewindespindel 11 ein Bund 19 vorgesehen, gegen den sich die Kugelumlaufmutter
14 anlegt, wodurch eine Beschädigung der Halterung der
Gewindespindel 11 und der Hohlwelle 7' vermieden wird. Dabei sorgt
weiterhin eine Rutschkupplung 18 dafür, daß die Wirkverbindung vom
Drehantrieb 10 über den Zahnriemen 9, die Führung 7, den Mitnehmer
15, die Kugelumlaufmutter 14, die Gewindespindel 11, den Zahnriemen
